Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a high-brake light guide bendability detection tool. Background Art

[0002] The high-brake light guide is a component at the top of the rear of the car and is an integral part of the brake light. It is separated from the position marker lights on both sides of the parking space and is set in a conspicuous position in the middle and upper area of ​​the rear of the car, which can more conveniently and effectively play a warning role. The transmission carrier of light guide technology is usually glass, flexible plastic film or injection molded light guide plate, light guide strip, etc. For the high-brake light guide, its overall shape is a horizontal rod, but it has a certain curvature on the side to adapt to the structure of the rear of the car; therefore, the produced high-brake light guide needs to be tested for bendability to ensure that its quality meets the applicable standards.

[0003] In the prior art, the fixture for testing the bendability of high-brake light guides has a relatively fixed clamping component, which cannot effectively fix light guide workpieces of different lengths, and the single fixing direction cannot effectively ensure the stability of the installation of the light guide workpiece. In addition, since the force acting on the workpiece during the detection process cannot be accurately applied to the midpoint position of the light guide workpiece, the measured data is not accurate enough, which affects the final bendability test result. Therefore, a high-brake light guide bendability test fixture is proposed. Utility Model Content
